您是否开了“硬件解码”呢？建议您关闭后台程序，并确认图传信道噪声是否过大。

APP显示正常，但是延时严重，3秒——4秒的样子。没有升级到1.4固件之前一切正常，升级后就出现延时。

同样的mini3在另外一台4K上没有问题。就是出现延时4K果断不升级了

画面卡顿和移动设备有关系 :D:D

楼主您好，从您的TXT文件看 ========== 2014.01.01 00:00:12 remo-con disconnect====== Packet: P3S_FW_V01.03.0020.bin Upgrading ... Result: Success. 您的当前固件版本为1.3.2，飞机在升级到1.4.1后可以回退至1.3.2，不可回退至1.2.8，因此您回退至1.2.8的操作无效，您APP“关于”界面如何显示呢？

楼主您能否把SD卡中的TXT文件截图发上来呢？
